Germ cell tumor(GCT)of the liver is extremely rare. Here,we describe a case of hepatic mixed GCT with significant sarcomatous components and elevated serum α-fetoprotein(AFP)in a 34-year-old ***,the tumor was composed of two GCTs components:yolk sac tumor and immature *** predominant components of immature teratoma consisted of several types of tissue that represented different germinal layers(endoderm,mesoderm and ectoderm) and showed varying degrees of differentiation with significant sarcomatous *** yolk sac component showed positivity for AFP and cytokeratin(AE1/ AE3).The immature teratoma components showed positivity for varying differentiation *** cytogenetic analysis revealed that the yolk sac tumor and immature teratoma were positive for i(12p)and 12p *** particular,the rhabdomyoblastic components also showed typical i(12p)and 12p *** suggested that sarcomatous components may be associated with dedifferentiation or malignant transformation of certain mesenchymal components within teratoma.

In Andre Lefevere＇s ＂Chinese and Western thinking on translation＂, he has compared the Chinese translation tradition with the tradition of the Western translation. Historically and culturally, he views the similarities and the differences between these two traditions, which has shed much light on extending the horizons of translation studies in China. However, some of his points put forward in the article need a further consideration. The author has a few doubts about the essay and offers her own different opinions.

AIM:To analyze the radiological features of multiple primary carcinoma (MPC) in the upper gastrointestinal (GI) tract,study its biological characteristics and evaluate X-ray examination in its diagnosis. METHODS:Hypotonic double-contrast GI radiography was performed in 59 multiple primary carcinoma cases,pathologically proved by surgery or endoscopy biopsy. Radiological findings were analyzed. RESULTS:Of the 59 cases,esophageal MPC (EMPC) was seen in 24,esophageal and gastric MPC (EGMPC) in 27 and gastric MPC (GMPC) in 8. Of the 49 lesions found in 24 EMPC,hyperplastic type was seen in 23,medullary type in 9. The lesions were located at the upper (n = 17),middle (n = 19) or lower (n = 13) segment of the esophagus. In 27 EGMPC,the esophageal lesions were located at the middle (n = 16) or lower (n = 11) segment of the esophagus,while the gastric le-sions were located at the gastric cardia (n = 16),fundus (n = 1),body (n = 3) and antrum (n = 7). The esophageal lesions were mainly of the hyperplastic type (n = 12) or medullary type (n = 7),while the gastric lesions were mainly of the hyperplastic type (n = 18). A total of 119 lesions in the 59 patients with synchronous multiple carcinoma were proved by surgery or endoscopy biopsy,and preoperative upper radiographic examination detected 100 of them (84.03% sensitivity). Eighteen (52.94%) of the T1 lesions were found during preoperative diagnosis by radiographic examination. Moreover,only 3 (3.53%) of the T2-4 lesions were misdiagnosed. CONCLUSION:Hypotonic double-contrast upper gastrointestinal examination,providing accurate information about lesion morphology,location and size,can serve as a sensitive technique for the preoperative diagnosis of MPC.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

The Arabidopsis Di19 （Drought-induced） gene family encodes seven Cys2/His2-type zinc-finger proteins, most with unknown functions. Here, we report that Di19 functioned as a transcriptional regulator and was involved in Arabidopsis responses to drought stress through up-regulation of pathogenesis-related PR1, PR2, and PR5 gene expres- sions. The Di19 T-DNA insertion mutant di19 was much more sensitive to drought stress, whereas the Di19-overexpressing lines were much more tolerant to drought stress compared with wild-type plants. Di19 exhibited transactivation activity in our yeast assay, and its transactivation activity was further confirmed in vivo. DNA-binding analysis revealed that Di19 could bind to the TACA（A/G）T element and chromatin immunoprecipitation （CHIP） assays demonstrated that Di19 could bind to the TACA（A/G）T element within the PR1, PR2, and PR5 promoters, qRT-PCR results showed that Di19 promoted the expressions of PR1, PR2, and PRS, and these heightened expressions were enhanced by CPK11, which interacted with Di19 in the nucleus. Similarly to the Di19-overexpressing line, PRI-, PR2-, and PRS-overexpressing lines also showed the drought-tolerant phenotype. The pre-treatment with salicylic acid analogs INA can enhance plants＇ drought tolerance. Taken together, these data demonstrate that Di19, a new type of transcription factor, directly up-regulates the expres- sions of PR1, PR2, and PR5 in response to drought stress, and its transactivation activity is enhanced by CPK11.

针对太阳、地球、月亮这些星球的活动对发生冲击地压的影响问题,采用理论分析及实例验证的方法,主要研究了由于地球自转速度的变化而引起地球上不同纬度间的应力差对发生冲击地压的影响,在一年中容易发生冲击地压的月份,太阳活动对发生矿震的影响,以及月球-太阳潮应力对发生冲击地压的影响。结果表明星球活动能明显地改变地壳的应力状态,进而影响冲击地压的发生,所以是控制冲击地压发生的一个重要因素。太阳、地球及月亮这些星球的活动对矿井处于临界失稳状态的煤岩体发生冲击地压有显著的作用。
